我上面写错了个地方！我是想问B和D 有什么区别

--Catherine,i have cleaned the room for you.--Thanks.you____it.I could manage it myselfA.needn't doB.needn't have doneC.mustn't doD.shouldn't have done选哪个（B和C有什么区别?有B这种说法吗?）我上面写错了个地方！我是想问B
选B

首先排除C、D.C选项表示不可以做,有禁止的意思,而D选项是不应该做,也有责怪的意思,显然C和D都是错的（人家帮你干了家务还怪别人! - -||| 从上Thanks可知,Catherine是感谢的,当然不是责怪啦.)
剩下A、B了.那么A、B有什么区别呢?在于时间.B选项情态动词+have done用虚拟语气表示对过去所做事情的态度,比如B项needn't have done,就是表示不必,虽然A、B项都有不必的意思,但是clean的动作已经过去了,所以B比A更好.因此选B.
翻译：——Catherine,我已经帮你打扫了房间了.
——谢谢.你其实没有不要去打扫,我自己来就行了.
P.S:楼上的楼上有小错误（You needn't have go to shcool today. Today is Sunday中的have go to shcool应改成have gone to school）

B 。。这个叫啥时态我真忘了。。。虚拟完成时？？？
意思是说你本来不需要这么做的。（其实已经完成了）

有B这种说法。唯一没有的是mustn't have done
B：本不必做
c：不许做

选B A为不必做 B为本不必要做而做了 C为禁止做 D为本不该做而做了

当然是选B,而且我也可以很明确的告诉你：有B这种说法。
B：指“你本没必要做（但却做了）”，含责备的语气
C：指“禁止你做，不准做”
结合语境，可知答案为B。

B
B的意思是本不需要做却做了
C是禁止做
要是选C一句话翻译下来也不对啊

B是虚拟语气，表示本不必做却做了，
C是禁止做。
题目中第一个人已经说做过了，所以选B

b是你本不因该做
c是不应当做
一个委婉一个肯定

全部展开

B, needn't have done 表示对过去己发生的事情进行虚拟，意为“本没有必要做”，言外之义是“实际上做了”，类似的结构 should have done 本应该做而没做， shouldn't have done 本不该做而做了
举个例子吧： You needn't have go to shcool today. Today is Sunday.意思是：你今天本没有必要去学校的，今天是星期天。（内含：实际上他去了）
比较：You needn't go to school today.Today is Sunday.意思：你不必去学校，今天是星期天（还没去）
C. mustn't do 表“禁止，不许” You mustn't be late.你不许迟到。

收起

b是你本不必做
c是不准做
d是本不应该做

need必要
should应该
